Title: Magnetic recording medium
Inventor: RYOMO KATSUMI
IPC: G11B5/702
Filed: 1986-04-14
Abstract: PURPOSE:To effectively prevent the generation of drop-out by providing a magnetic layer dispersed with ferromagnetic powder into a binder on a nonmagnetic base and using a polyisocyanate isocyanurate as a curing component for the binder. CONSTITUTION:This magnetic recording medium is formed by providing the magnetic layer dispersed with the ferromagnetic powder in the binder on the nonmagnetic base. The polyisocyanate isocyanurate is used as the curing component for the binder of the magnetic layer at a content of 1-50wt% of the total weight of the binder. Carbon black is incorporated into the magnetic layer. Electrification of a traveling system is thus decreased and the generation of the drop-out is effectively prevented.

Title: Electron beam exposing method
Inventor: OKINO TERUAKI
IPC: H01L21/027
Filed: 1980-06-23
Abstract: PURPOSE:To precisely expose a microminiature pattern by varying the quantity of electron beam emitted to the respective positions of a resist layer in accordance with time to allow the positions to be emitted to be left in vacuum after the emission of the electron beam and equalizing the progresses of crosslinking reactions at the respective positions of the resist layer. CONSTITUTION:An electron beam emitted from an electron gun 11 is converged, deflected and emitted to a substrate 18 on which an electron beam sensitive resist is, for example, coated, and an extremely small pattern is sequentially exposed on  the respective positions on the substrate 18. The relationship between the vacuum leaving time and the exposure sensitivity is stored in advance in a computer 20 for  controlling the emitting conditions or the like of the electron beam in the exposing step, and the quantity of the electron beam at the respective positions is controlled corresponding to the time from the emission of the positions to be emitted to the time in which it is taken out of the vacuum. For instance, it is controlled to lengthen the emitting time at the position in which the leaving time is, for example, shortened and the sensitivity is lowered. Since the difference of the sensitivity depending  upon the positions to be emitted on the substrate can be compensated in this manner, the extremely small pattern can be precisely exposed.

IPC: G11B5/265
Filed: 1997-03-19
Abstract: PROBLEM TO BE SOLVED: To provide a perpendicular magnetic recording composite head capable of suppressing deviation in recording tracks and reproducing tracks accompanying a skew angle change, improving high track density and reducing a cost with simple constitution. SOLUTION: A reproducing head 17 is arranged in the inside of a recording closed magnetic path 19 so that an upper part shield 3 is parallel to a main magnetic pole 23, and the upper part shield 3 and a lower part shield 1 are set to film thickness of 1-0.8 μm. Since a long distance between the recording head and reproducing head caused by a usual technique arranging the recording head and reproducing head side by side is shortened, even when the skew angle is changed, the matter that the deviation occurs between the tracks of the recording head 18 and reproducing head 17 is suppressed, and recording density in the track width direction and linear direction are improved, and high recording density is obtained. Since the upper part shield 3 and lower part shield 1 are thinned, manufacture is facilitated, and thereby a device is made at a low cost.
